Fellusive has released a free synthesizer instrument for Mac as part of the KVR Developer Challenge 2021.

Nettle explores the unique and relatively under-explored world of scanned synthesis.

The timbre of the sounds you create constantly evolve, as the waveform produced is made by tracing (scanning) the positions of masses that are always in motion. These masses are set into motion when you press a key on your MIDI controller – this simulates the action of a hammer striking the connection of masses. Through the user’s manipulation of the masses, the springs that connect them, and the hammer that excites them, a wide range of dynamic, almost sentient, sounds are possible.

Nettle features

  • 32-voice polyphony.
  • Fully automatable knobs.
  • Filter (low-pass, high-pass) and reverb available for signal processing.
  • Four LFOs and ADSRs available for modulation, along with two sources for modulation via your MIDI controller.
  • Built-in presets, as well as the ability for users to save and modify their own presets.
  • A randomize button.

The plugin is available in VST and AU formats for macOS. You can download it for free from KVR Audio and at Fellusive’s Gumroad page, where you can also optionally pay for it in support of developer Jason’s work.
